Summaries for Prolonged Electroretinal Response Suppression

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 75374Disease definitionBradyopsia is characterised by prolonged electroretinal response suppression leading to difficulties adjusting to changes in luminance, normal to subnormal acuity and photophobia.EpidemiologyIt has been described in five unrelated patients with symptoms present since childhood.EtiologyThe disorder is caused by recessive mutations in the RGS9 (chromosome 17q23-q24) or R9AP (chromosome 19q13.11) genes.Visit the Orphanet disease page for more resources.

MalaCards based summary : Prolonged Electroretinal Response Suppression, also known as bradyopsia, is related to dermatopathia pigmentosa reticularis and leber congenital amaurosis 1. An important gene associated with Prolonged Electroretinal Response Suppression is RGS9 (Regulator Of G Protein Signaling 9), and among its related pathways/superpathways are Phototransduction and Metabolism of fat-soluble vitamins. Affiliated tissues include eye, and related phenotypes are visual impairment and photophobia

Disease Ontology : 12 A retinal disease characterized by the slower than usual adaptation of the eyes to changing light conditions; can have material basis in mutations in the RGS9 or the R9AP genes.

Genetics Home Reference : 25 Bradyopsia is a rare condition that affects vision. The term "bradyopsia" is from the Greek words for slow vision. In affected individuals, the eyes adapt more slowly than usual to changing light conditions. For example, people with this condition are blinded for several seconds when going from a dark environment into a bright one, such as when walking out of a darkened movie theater into daylight. Their eyes also have trouble adapting from bright light to dark conditions, such as when driving into a dark tunnel on a sunny day.

UniProtKB/Swiss-Prot : 75 Prolonged electroretinal response suppression: Characterized by difficulty adjusting to sudden changes in luminance levels mediated by cones.
